HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 748,995, dated January 5, 1904.

Application filed March 12, 1903.

Serial No. 1 17,3531. (N model.)

To all whom it may concern:

Be it known that I, NATHAN R. SPAULDING, acitize'n of theUnited States,residing at Monroeville, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Heating-Stoves; and I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to !0 which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of ref erence marked thereon, which form a part of this specification.

This invention relates to improvements in heating-stoves; -and the object thereof is to utilize the heat as it passes from the firecha'mber to heat an increased radiating-surface.

I accomplish my object by the construction illustrated in the accompanying drawings, in which- I Figure 1 is a vertical central section. Fig. 2 is a cross-section on the line X X of Fig. 1. Fig. 3 is a plan, and Fig. 4 is a perspective view, showinga modified form of end casting. Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, 1 is the 3': top of the stove, 2 is the base, and 3 is the end casting. The outer shell 1 ranges between the top and base, and the ends thereof are secured to the back of the end'casting 3. The inner shell 5 ranges between the said top 5 and base and incloses the fire -chamber 9. The ends of said inner shell are secured .to the front of the end casting 3; An intermediate partition 6 ranges between the outer shell 4 and inner shell 5 and extends from 0 the said top to the base, its ends being secured to the front of the end casting 3 at points coincident with the ends of the inner shell" 5. Thus a flue-chamber 7 is formed between the outer shell and partition and a heating-chamber 8 between the partition 6 and inner shell 5. A series of openings 10 are made in the top 1 and another series of openings 11 extend through the base 2. All of said openings range in line with and communicate with the heating-chamber 8.

The end casting 3 has a lateral partition 12, l 6,

which divides said end casting and forms therein an upper chamber 13 and lower chamber 14. An opening 15 extends through the front of the end casting and affords communication from the fire-chamber into the lower chamber 14: of said end casting. An opening 16 leads from the lower chamber 14 into one end of the flue-chamber 7, and another opening 17 affords communication from the other end of said flue-chamberinto the upper chamber 13. An exit-opening 18 is made in, the top 1, which affords communication from the upper chamber 13 into the stovepipe 19. An air-inlet pipe 20 extends downward through the top 1 and ranges in the heating-chamber 7 and passes through the inner 'shell 5 into the fire-chamber 9. A damper 21 is arranged at the top of the pipe 20 to regulate the passage of air into the fire-chamber through said pipe.

A box 22 is arranged beneath the base 2 and is provided with a door 24 at its forward end. A removable ash-receptacle 23 is placed in said box to receive ashes from the firechamber 9 as the same pass therefrom through the grate 25, which is arranged in the base 2. A rod .26 passes under the base 2 into the box 22 and is attached to the grate 25, so that the said grate may be shaken thereby to assist the passage of ashes from the fire-chamber.

In the. modification shown in Fig. 1 the lower right-hand side B of the end casting A is open, as is the upper left-hand side 0. The walls D and E continue from the ends of the partition F and close, respectively, the lower left-hand side and the upper right-hand side of said end casting.

In the operation of my invention fuel is introduced into the fire-chamber through the door 27, and as fire is started a proper quantit-y of air is allowed to enter the fire-chamber through the pipe 20. The products of combustion pass from the tire-chamber through the opening 15 and 16 into the flue-chamber 7, from whence they pass through the opening 17 and are discharged through the stovepipe 19, their course being indicated by the arrows. (Shown in Fig. 2.) The air in the heating-chamber 8 becomes heated by radiation from the inner shell 5 and the partition and consequently rises and passes out through the openings 10 in the top 1 and is replaced by a draft of air entering the heating-chamber through the openings 11 in the base. It is obviousthat the outer shell 4 also 5 affords a radiating-surface because of the passage of heat through the flue-chamber 7.

' I have also shown a reinforcing-plate 28 at theforwardendofthefire-chamber9. Thesaid plate has lateral flanges 29 at its edges, which IO are adapted to hold the lining-sheets 30 in position. Projections 31 extend forward fIOIIL claim as new, and desire to secure by Letters Patent, is

In a heating-stove, a top; a base; an end casting extending from the base to the top 25 communication with said lower chamber and 30 1 ing-sheets 30 may be renewed when desired :5 by springing the same inward in the firechamber, so as to release their ends from the In testimony whereof I affix my signature in presence of two witnesses.
